I used a sleeveless baby shirt as a pattern for the top, and just cut it longer to create a dress.
Remembering to leave extra room for seam allowance, I cut two of each.
Placing one of each pattern face to face, I sewed along the edges of the sides, arm holes, shoulder straps, and neck. I left the bottom open.
After turning this piece right side out, I top stitched along the arm holes, shoulder straps, and neck. (top stitching is optional, but it does give the piece a more finished look). I left the sides plain.
To deal with the open bottom, I tucked the edges of the fabric inside and pinned it in place to top
Follow all previous steps for the other side.
Placing the two halves (same side up) together on one side, I ran a long stitch connecting them together (thus why there was no need to top stitch the sides previously). I repeated this on the other side.
After cutting off any extra thread, I tied the two shoulder straps together to create a knot.
I now have a sweet reversible dress for Squirrely!
